Upgrading telephone exchanges


BT simplifies the upgrade of FTTH telephone exchanges with this flatpack-delivered Optical Consolidation Rack

Upgrading telephone exchanges

For its ongoing BTOpenreach program BT chooses Prysmian Group as its preferred partner to turn an innovative OCR Exchange concept into reality. BT and Prysmian Group co-designed the OAsys Optical Consolidation Rack to upgrade BT telephone exchanges around the country.

Special feature – they allow splicing of network fibre to pre-connectorised cables thus avoiding the need for individual cable jumpers. The OCR is a splice-only solution for FTTH PON networks with multiple customers on the same fibre to eliminate congestion. Delivered in a flat pack format the units can be assembled easily by one person.

The OCRs accommodate up to 8 sub-racks with 12 pull-out modules and 6 splice trays. Their total capacity allows 1152 fibres on a dual fibre per tray basis.
